SPECIFICATION forming part of Letters Patent No. 410,841, dated September 10, 1889.

Application filed December 10, 1888- Serial No. 293,110- (No model.) I

To all whom it may concern.-

Be it known that we, WILLIAM A. LORENZ and, EDWARD E. CLAUSSEN, of Hartford, Connecticut, have jointly invented certain new and useful Improvementsin Paper-Bag Machines, of which the following description and claims constitute the specification, and which is illustrated by the accompanying six sheets of drawings.

These improvements are particularly applicable to the paper-bag machine which is shown in Letters Patent of the United States, No. 361,951, to Lorenz and I-Ioniss, of April 26, 1887, and they consist in mechanism to make the diamond fold described in that patent, and in mechanism for delivering the diamondfold blank from one traveling folding-bed to another.

Figures 1, 2, and 3 of the drawings are a plan, a side, and an end View, respectively, of a portion of a tucked paper-tube, which is called by us a blank. Fig.4: is a side View of this blank pressed together near its center. Figs. 5 and 6 are a side and a plan view of the blank, showing one end opened up into a boxlike form. Figs. 7 .and 8 are a side and a plan View of the blank, showingthe box-like form partly folded down into the shape which we term the-diamond. Figs. 9 and 10 are a side and aplan view of the same, fully folded down. Fig. 11 is aplan of the machine. Fig. 12 is partly a side View thereof and partly a vertical section on the line a b of Fig. 11. Fig. 13 is a rear end View of the left-hand portion of Figs. 11 and 12, looking from left to right. Fig. 14 is a side view of portions of Fig. 12, with abag folded into the box-like form. Figs. 15 and 16 are a plan and aside view, respectively, of the upper portion of the machine, showing thebag folded into the diamond form. Figs. 17 and 18 are a side and an end view of a modified form of the diamond-folding mechanism. Figs. 19 and 20 are an end and a side View of another such modification. Figs. 21 and 22 show the same modification in another position.

For greater clearness, the gears 36, 37, 88, and 39 are not shown in full in side view,but have teeth omitted.

The numeral 1 indicates a bag-blank severed from a continuous tucked paper-tube, and having two inwardly-projecting tucks 2 and 3, and longitudinal slits 4 and 5, a lip 6, a corresponding recess 7, the tucks extending the entire length of the blank, and the slits extending only a short distance into one end thereof, as shown in Figs. 1 and 3. The form which we call the box is that shown in Figs. 5 and 6, and is marked with the numeral 8. The form which we call the diamond is that shown inFigs.

with the numeral 9.

In this machine a blank is being delivered to a traveling folding-bed and the box form 7 to 10, and is marked is first folded, then the diamond form is folded, and then the partly-folded bag is delivered to another traveling folding-bed,where subsequent operations may be performed thereon.

The two traveling folding-beds are made in the form of a rocking carriage and a revolving cylinder, respectively, and are similar to the two beds shown and described in said Letters Patent No. 361,951; but in that patent there is shown intermediate rolls that grip and pass the bag from the first to the second bed, while in this machine these intermediate rolls are omitted. The rocking carriage has three mechanisms attached to it,

which are similar in form and in operation to those described in said Letters Patent No. 361,951, and they compose a presser-plate mechanism, a tuck-entering mechanism, and a blade-folding mechanism, and the carriage itself is oscillated by a crank and connectingrod, as shown in that patent.

The carriage is indicated by the numeral 80, is pivoted on a shaft 81, and is worked forward and backward by a connecting-rod 78. Upon the upper part of the carriage 80 0 there is a presser-plate 98, secured to two brackets 100 and 101, which brackets receive vertical motion from two presser-arms 102 and 103, which are fixed to a rocking shaft 104, and which carry pins 105 and 106,which the shaft 104:, at the outer end of the cartuck-levers.

riage 80, there is attached an arm 109, to which is pivoted a connccting-rod 1.10, which receives motion like that shown in said Letters Patent No. 361,951.

The carriage 80 has two cars 118 and 119, carrying fixed studs 120 and 121, upon which are placed the two rocking tuck-levers 122 and 123, carrying cam-rolls 126 and 127 ,whieh run in cam-grooves 12S and 129 of cams 130 and 131, which cams are attached to the gears 85 and 36, running upon the shaft 81 at both sides of the carriage 80. To the upperend of these tuck-levers 122 and 123 are secured tuck-blades 1.32 and 133, which have angulir ends projecting inwardly toward the center of the machine, and these blades receive a reciprocating motion in and out from the car riage 80 as the cams 130 and 131 revolve.

In the upper ends of the tuck-levers 122 and 123 are placed two shafts 131 and 135, to which are secured box-blades 136 and 137, which also have angular ends. These blades 136 and 137 are opcratively connected with a cam on the shaft 81, and receive therefrom a rotary reciprocating motion of about one hundred and eighty degrees, as shown in Figs. 11 and 16, respectively. This movement is attained by means of pinions 13S and 139, iixed on the box-blade shafts 131 and 135 and driven by the racks 110 and 111, which slide in casings attached to the upper ends of the These racks are operated by means of connecting-rods 112 and 113, which are connected at the pivots 111 and 115 to es ci1latinglevers116 and 117. These oscillating levers swing upon the hubs of the tuclelevers 122 and 123, which oscillate upon the studs 120 and 121. The opposite ends of the oscillating levers 116 and 117 are bevelscc tors, which mesh into bevel-sector arms 11S and 119, fastened to the shaft 150, which oseillates in cars in the carriage 80.

To the outer end of the shaft 150 is secured the arm 151, carrying a pin 152, upon which a roller 153 revolves, engaging in a cam-groove 151 in the cam 155, which cam is fixed to the other cam 130 and revolves with it, thus transmitting an oscillating motion simultaneously to the arms 116 and 117, and through them giving oscillating motion to the box-blades 136 and 137. The tuclelevers 122 and 123 and the levers 116 and 117 are all held upon the studs 120 and 121 by the collars 156 and 157. The tuck-levers 122 and 123 receive the proper oscillating motion from the cams 130 and 131 at suitable intervals, thus driving the blades attached to their upper ends to and from the carriage. The levers 116 and 117 also receive a proper oscillating motion from the cam 155 at suitable intervals, transmitting an oscillating motion to the box-blades 136 and 137, all of which motions occur during the rocking motion of the carriage 80.

The new mechanism for folding the boxlike form into the diamond form is as follows:

Arranged on the upper part of the carriage 80 are two side plates 10 and 11, secured to shafts 12 and 13 in brackets 11 and 15, which are fastened to the carriage. On the shafts 12 and 13 are two bevel sector-pinions 16 and 17, meshing into bevel sector-arms 20 and 21. These arms are fixed to a cross-shaft 18, and from the arm 21 astud 22 projects and is pivoted to the connecting-rod 23, the other end of which is pivoted by the pin 21 to the side lever 25, which is pivoted to a stud 26 in the carriage 80. The lower end of the lever is marked 27, and has a projection which enters a cam-groove 28 of the cam 29, which is fixed to the shaft 81. The side plates 10 and 111eceive the proper oscillating motion simultaneously from the cam 29 at suitable intervals, thus driving the plates through an arc of about ninety degrees from the position shown in Figs. 11, 12, and 13 to that shown in Figs. 15 and 16.

The cylinder 32 is secured to a shaft 33, which revolves in bearings 15 and 16, which are part of the uprights 31 and 35. The shaft is driven by means of a gear 36, which derives motion from a gear 37 on the shaft 81, and the timing is so arranged that the cylinder 32 makes one revolution to two oscillations of the carriage 80. The object of this is to work two sets of gripping devices on the cylinder; but one set may be employed, if preferred, and the cylinder may be come spondingly reduced in diameter.

The new mechanism for delivering the diamond-fold blank to the cylinder is as follows: Fastened to the uprights 31 and are two rods 11 and 12, which hold two plates 13 and 11 over the cylinder. Upon the projecting hubs 15 and 16 of the uprights are fixed two cams 19 and 18, respectively. The cam 19 is provided wi th the cam-groove 50, which works the arms 51 and 52, the shafts 53 and 51, and the lower grippers 55 and 56. These shafts are on opposite sides of the cylinder, and these grippers have bifurcated ends 57, which rise beyond the surface of the cylinder and fall back even with that surface. The cam 18 is provided with the opposite cam ends 58 and 59, the contours of which ends are shown by dotted lines in Fig. 12, and those cam ends alternately lift the arms 60 and 61 against the resistance of the springs 62 and (3, respectively, and thus work the shafts 61 and 65, together with the grippers 66 and 67, fixed thereto, and these springs press the ends 68 of the upper grippers 66 and 67 down upon the ends 57 of the lower grippers 55 and 56, whenever neither of the said cam-ends is lift in g the upper grippers.

The operation of this machine is as follows: As bag-blank 1, having been fed into the up per-part of the carriage 80 and gripped by the presser-plate 9S, and the two pairs of blades 131 and 136 and 133 and 137 having entered the tuck-recesses 2 and 3 of the blank, as shown in Figs. 11 and 12, and the two blades 136 and 137 having been oscillated about one hundred and eighty degrees, as shown in Fig. 1.1, a box-like form 8 will have been folded up in the same manner as that shown in said Letters Patent No. 361,951. The side plates 10 and 11 then fold down from the position shown in Fig. 14 to that of Figs. 15 and 16, and thus fold the box-like form 8 into the diamond form 9. The front end of the diamond form is then carried forward by the carriage and inserted between the ends 57 and 68 of the grippers 55 and 56, and then the upper gripper 68 is forced by the spring 62 down upon the forward end of the diamond form, thus gripping the bag-blank firmly, as shown in Figs. 15 and 16. The various blades attached to the carriage then release the bag-blank, the side plates 10 and 11 rise to their upper position, and the bag-blank is drawn forward upon the cylinder 32. Meanwhile the lower gripper, 55, followed by the upper gripper 66, is dropped to the level of the cylinder-surface, so that the bag may lie upon it, and the diamond-folded bag-blank is drawn by the grippers 55 "and 66 under plates 43 and 44, to'preserve its folded flatness and to aid in holding it down upon the cylinder. Thus delivered to the cylinder the bag-blank may be operated upon, as in said Letters Patent No. 361,951.

A modified form of gearing for working the side plates 10 and 11 is shown in Figs. 17 and 18. Here the side plates are attached to shafts 12 and 13, rocking in brackets 14 and 15, and secured to the shafts 12 and 13 are sectorpinions and 91, meshing into racks 88 and 89, sliding in brackets 14 and 15. Meshing at right angles into these racks are sector-gears 85 and 86, fastened to a cross shaft 18, to which an arm 87 is also secured. Atthe end of this arm, on a pin 92, is attached the connectingrod 23, which derives motion in a manner similar to that before described. Other methods of connecting the parts together may also be employed.

A modified form of side plates is shown in Figs. 19 to 22. Here the two side plates 158 and 159 are hung over the top of the carriage 80, the plates being supported and swung on studs 160 and 161, these latter being fastened in brackets 162 and 163, which are projections of the carriage 80. Fastened to the side plates 158 and 159 are two bevel-sectors 164 and 165, which engage with sector-arms 166 and 167, which are secured to a cross-shaft 168, which is also supported in bearings inv the brackets 162 and 163. Oscillating motion is given to the plates through the sectors by means of a rod 169 on the stud 170, which stud is driven into the sector 167. The rod 169 derives its motion in the same manner and at the same time that the rod 23 does. In Figs. 19 and 20 the bag is shown folded as far as the box-like form 8, the side plates 158 and 159 being swung open, and in Figs. 21 and 22 the side plates are swung in, converting the box-like form 8 into the diamond form 9.

\Ve claim as our joint invention 1. The combination of the rocking carriage 80, the side plates 10 and 11, rocking toward each other above that carriage and at right angles to the rocking thereof, and the cam 29, and mechanism, substantially as described, between that cam and those side plates and operating to work the latter, all substantially as described.
